To all whom, t may concern.'

Be it known that l, EMILIEN D. SAINT CYR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gaseous-Fuel Mixers, of which the following is a specification.

My invention relates to a device for mixing vaporizing liquid fuels and the object thereof is to provide simple and efficient means for rapidly and perfectly vaporizing and mixing the fuel.

Speaking in general terms the device constituting an embodiment of my invention consists of a strip of fine metal gauze, preferably corrugated and rolled upon itself until. the diameter of the roll is sufficient to lill the space or cavity chosen as the vapori :aing chamber which may be located anywhere between the needle valve or aspirating nozzle of any suitable form of carbureter and the cylinders of the motor. ln practice asuitable top and bottom preferably made of metal gauze of coarser mesh is added to hold the different layers of the rolled-up structure and means are also provided to hold the entire device in proper position in such vaporizing chamber.

The construction and arrangement of the device is such that the fuel as it issues from the carbnreter is sprayed upon the gauze fabric and is spread over the extremely large surface presented by such fabric with the result that it is rapidly and effectually vaporized by the reduction of the atmospheric pressure caused by the suction produced by the pistons of the motor and also vaporized by the strong current of air resulting from such suction. The fuel is then introduced into the motor as a perfectly vaporized and mixed fuel.

lnasmuch as the device is made of metal theheat of the adjacent parts is readily conducted thereto which materially assists in the vaporizing action.

By the use of my device a perfect and uniform vaporization and mixture is obtained thereby resulting in (l) increased power, (2) ease of starting, (3) utilization of cheaper and lower grade fuels, (4) economy in quantity of fuel used for the same mileage, (5) less carbonization in the cylinders, (6) greater flexibility of motor. In addition, by use of my device, all danger-of lire due to back-firing through the carbureter is eliminated.

In the drawing Figure l is an elevation .of

the same representing one embodiment of my invention; Fig. 2 an elevation of the device removed from the intake pipe and shown on a larger scale than in Fig. l; Fig. 3 a cross section ofthe device but on a larger scale than Figs. l and 2; Fig. 4 a detail edge view of the gauze fabric which is corrugated in the preferred manner, that is on the bias; Fig. 5 an elevation of the angularly'corru-l gated fabric extended; Fig. 6 an edge View of a plaited form of fabric; Fig. 7 a View similar to Fig. 2 but illustrating the gauze fabric shown in Fig. 8: Fig. 8 a view similar to Fig. 5 but illustrating a fabric having cross corrugations or pla-its; Fig. 9 a View similar to Fig. 2 but illustrating a different form of attachment, and Fig. 10 a cross section of a modified form of device.

My invention may be embodied in different forms and for the purposes of a' clear and definite disclosure of my invention l have illustrated two embodiments thereof Without intention of limiting mv invention in its broader aspect thereto. Moreover, it will be understood that my device may be presented in any suitable location for accomplishing the desired result and may be associated with any suitable character of carbureter, the one herein shown being simply selected as a conventional one for illustrative purposes.

Referring to the embodiment of my invention as illustrated in Figs. l to 5 my device is in the form of a cylinder inasmuch as it is here interposed in the cylindrical passage of the fuel intake pipe l connecting between the carbureter 2 and the engine manifold 3. rlhe body of the device is formed of a strip of Wire gauze 4 such as illustrated in Fig. 5 according to which and by preference the fabric is provided with suitably-formed and shaped corrugations 5 which extend thereacross on the bia-s, that is at an angle to the length and Width thereof. These corrugations may be plain or they may be made like the plaits 5a shovvn inFig. 6. A strip'of this gauze fabric 4of suitablev Width is thus corrugated. and then rolled dimly ontightly; upon itselii into cylindrical ormD the fabric being of a length to make the proper di ameter of roll or cylinder so as to ll up the cavity or conduit in which it is placed.

ln order that the cylinder of gauze may.i be held together and be a contained articlevvhchcan be handled like a cartridge torv instance and also t increase the vaporizing surface, l preter to provide the bottom and top of the cylinder with metal gauze abrie preferably of somewhat coarser or larger f the cylinder mesh, although it may loel 'sudicient ityonly oneend ot the cylinder, be thus bound. 'llhis coarser gauze is preferably termed :tor 4the top as a cap 6 :Fitting over theA top, proper and also partially along the sides, the same being secured to the c linderfin any suitable mane` ner as by soldering along the line 6'. vln like manner the coarsertabric for the bottom ot is formed as a cap PZ and such cap -is secured to the cylinder inf-suitable manner as by soldering and in addition there is secured to the cylinder by soldering or otherwise a ring 8 here shown 'as a spring ring having a depending flange 8 which provides a means tor securing the device in place in the `intake pipe. As shown in lFig. l this flange is clamped between the llanges 2 and la ot the carburetor and intake pipe respectively although it will be understood that my invention in' its broader aspect is not v ings so that in the limited to this particular manner of attachment. lf desired, the attaching means may be in the form of a gasket 8* as shown in 9, such gasket being adapted to be clamped between said flanges l and 2e. 'lhis may be secured to the body ot the device at any desired place along the length thereoit in order to adjust such device toward or away from the 'carburetor according to the position ot its nozzle.

Although ll prefer the diagonal or bias running of the plaits or corrugations as shown in Fig.) 5, yet if desired these corrugations t may run transversely oi' the strip as illustrated in vlligs. 7 and 8. las a matter ot tact some measure oi my invention may be obtained by omitting the plaits or corrugations altogether and merely rolling up the plain gauze fabricA into cylindrical -iorm and by preference providing the end capor capsv as described.

By preference and as shown the corrugations or plaits are constricted at their openrolling operation they will not intermesh thereby separating the layers oi' fabric and providing canals or conduits for the air and vapor. Although lt prefer to provide corrugations made from l the rolled 'labric itself., yet it is obvious that they may be formed by tubes oit gauze secured to the fabric by soldering orf-othervvise, such tubes being arranged diagonally it that formation is desired. inasmuch as arrasar thecorrugations are usetill to provide a plurahty of passages, either straight or at an angle, it is obvious that such passages may be formed by omitting the strip and using a plurality ot' gauze tubes hunched and connected together. Furthermore, it desired, the device may be produced by rolling up together a corrugated strip and a plain strip as seen in Fig. 3.0.

The device rovides the largest ossible amount ,ot surtace' upon vvhichthe liquid or duid .to be vaporized is s read and permits the'current ot air to reaegly cornev into contact-With the liquid thus spread out in thin ilm on the surface of the metallic gauze, (made Warm by conduction oit heat Jfrom the manifold and carburetor after the engine has been in operation), with the resuit that the liquid is quickly and perfectly vaporized and mixed and delivered in that condition to the cylinders. ln addition the formation of thin lms ot fuel in the innumerable minute openings in the gauze fabric still further facilitates vaporization.

Moreover, when the plaited or corrugated form ot' strip is employed in forming the cylinder there is no 'straight course but in the bias term of ccrrugation there is a spiral course or path,y which the sprayed or only partially vaporized fuel can follow so that such fuel will strike innumerable places in the gauze which causes the spreading ot the fuel to take place upon the large surface of the device. lt is not intended that the uel shall follow any one spiral path after enter ing the same at the bottom but that it may pass through the Walls ot the corrugations, following the path of least-resistance. Furthermore, the gauze Whose edges only are presented in the direction of the flow does not oder resistance to the 'intake ot" the mixture;

'By the use ot my device l am enabled to obtain the several .practical and advantageous results specied in the preamble ot this specification. llt will be understood that in the claims ll use the term l corrugated l in the broad or general sense.
